Interpretive Summary: In-furrow application of nitrogen and tillage before planting were more effective than chemical seed treatments to reduce Rhizoctonia root rot of spring wheat in a no-till system.

Technical Abstract:
In-furrow of application of nitrogen significantly reduced the seminal root rot rating and increased seedling height, length of the first leaf, and the number of seminal and crown roots compared to the control treatment. Plants from the tillage + Nitropak treatment had the lowest seminal root rot ratings and the greatest number of tillers and length of the first true leaves. However, these effects were not significantly different from the treatment with Nitropak alone. Seed treatment with Dynasty alone increased seedling height, but did not have a significant effect on number of roots or root rot ratings. In-fullow application of nitrogen was more effective than Dynasty seed treatment for promoting seeding growth and decreasing the severity of Rhizoctonia root rot.
